Flash Experts, I have a issue/question....

For a friend I am installing a TAM's pipe in his Flash. I was given the jet and the pipe....so me has questions!

How is this installed, exactly? Do I retain the original Flash outer pipe and slide the Tam Pipe inside? It seems like this is the ticket, however the pipe is not "snug" at the back end and can actually move up/down/right/left about a 1/16th of an inch.

Not sure how to proceed without fabricating new bulkheads and removing the original outer flash pipe.

Can anyone shed some light?[8D]
